Hi. Already wrote to them. Waiting for a response.

Didn't get any consulation nor did reviewers specify exactly what is the problem. My code is unique. I don't have any other app in my account, i haven't purchased any design, it's all by me.

That's the only app i have on my account. And i haven't sold my app to anyone. It was created a month ago.

Seems like it

yes, it is open source. I already tried. But i get general message from a bot

I don't think it is because of flutter. I have multiple only flutter apps that were published recently on other projects
